Hans full is pulling on a rope to drag his backpack to school across the ice. he pulls upwards with a force of 22.9 newtons at an angle of 35 degrees above the horizontal to drag his backpack a horizontal distance of 129 meters to the right. determine the work (in joules) done upon the backpack.

Next a skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 15 with the horizontal. the rope moves parallel to the slope with a constant speed of 0.69 m/s. the force of the rope does 800 3 of work on the skier as the skier moves a distance of 8.4 m up the incline. (a) if the rope moved with a constant speed of 2.2 m/s how much work would the force of the rope do on the skier as the skler moved a distance of 8.4 m up the incline? at what rate is the force of the rope doing work on the skier when the rope moves with a speed of (b) 0.69 m/s and (c) 2.2 m/s?

Aregion of space in which a measurable gravitational force is indicated by the force exerted on a test mass is called
